Ryobi Improves Its Cordless Brad Nailer With Updated Models
Of the five Ryobi nailers and staplers I've purchased, the one I get the most is my Ryobi Cordless 18 Gauge Brad Nailer. Ryobi have updated many of their cordless staplers, including the handy Ryobi P326 16ga nailer as well as the narrow crown stapler. After owning the first generation Ryobi P320, I got my hands on the new Ryobi P321 Cordless Brad Nailer to see what had changed compared to the old 18 gauge brad nailer.
advantage
- good build quality
- New tip allows for more precise nail placement
- Improved Ergonomics
- Better tool-free jam removal
- Work lights that can be activated without starting tools
- Drive 18 horn head from 5/8" to 2"
- ONE+ 18V battery for over 225 Ryobi tools
shortcoming
- Still can't drive the longest nails into hardwoods like oak
Ryobi P321 Cordless Brad Nailer Performance
Perhaps the most welcome change to the new Ryobi P321 Cordless Brad Nailer is the reduced size of the protective tip on the nose. It is 45% smaller than the old model. More precise nail placement comes in handy when shooting into thin moldings around doors and windows. Like all Ryobi cordless nailers, this one includes a replacement tip that stores on the tool.
A side-by-side comparison of the old and new Ryobi 18-gauge ball nailers shows a slight change in handle shape. Having used both, I have no preference for either controller. They all feel comfortable to use. Neither of these will give you any hot spots, even when used all day. I also like the huge "18" gray band for quick tool identification.

The new Ryobi P321 Cordless Brad Nailer drives 18 nails ranging in size from 5/8" to 2". Ryobi will make a sound when using this brad on plywood, plastic trim, cork, and similar building materials. It drives nails quickly and accurately. This is exactly what you've been looking for in a brad nailer.
It will drive nails of any length with no problem except the longest nails into hardwoods like oak. The more I test the nails, the more I appreciate the density and hardness of oak and maple. In my experience, only the best quality nail guns will drive the longest nails into these materials.

Ryobi P321 Cordless Brad Nailer Design Instructions
Since I have five nailers and staplers from the same manufacturer, they all look alike. It's hard to tell the difference between them. Ryobi has finally started adding a clear brand identity to help you differentiate them. Especially helpful is the addition of color-coded stickers near the magazine issue, clearly marking each peg.
One complaint I had with my old 18-gauge ball head nailer had to do with the power control knob. Located on top, I found it stiff and difficult to use if you have arthritis (as I do). The Ryobi P321 Cordless Brad Nailer replaces the knobs with easier-to-use rods. By the way, the new brad nailer also comes with a belt clip. Unfortunately, someone in the office seems to have misplaced it! You can attach the belt clip to either side of the tool.

Ryobi makes clearing paper jams even easier. The P321 now has a sleeker, more ergonomic release latch that allows the handpiece to open without any tools.

The Ryobi P321 Cordless 18 Horn Head Nailer should be on Home Depot shelves by the end of the year (2021). This tool will replace the P320 18 Gauge Corner Head Nailer. Hopefully you will also be able to purchase the kit version with battery charger and 2.0 Ah battery.

the bottom line
I've been happily using my old Ryobi brad nailer. New improvements make an already great tool even better. Anyone looking for a brad nailer should consider the new Ryobi P321 Cordless 18V Brad Nailer. Delivering great value and reliable performance for $129 — Ryobi has built its reputation on that.
